Answer 1

//Init the NSURLSession with a configuration 
NSURLSessionConfiguration *defaultConfigObject = [NSURLSessionConfiguration defaultSessionConfiguration]; 
NSURLSession *defaultSession = [NSURLSession sessionWithConfiguration: defaultConfigObject delegate: nil delegateQueue: [NSOperationQueue mainQueue]]; 

//Create an URLRequest 
NSURL *url = [NSURL URLWithString:@"yourURL"]; 
NSMutableURLRequest *urlRequest = [NSMutableURLRequest requestWithURL:url]; 

//Create POST Params and add it to HTTPBody 
NSString *params = @"api_key=APIKEY&email=example@example.com&password=password"; 
[urlRequest setHTTPMethod:@"POST"]; 
[urlRequest setHTTPBody:[params dataUsingEncoding:NSUTF8StringEncoding]]; 

//Create task 
NSURLSessionDataTask *dataTask = [defaultSession dataTaskWithRequest:urlRequest completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) { 
    //Handle your response here 
}]; 

[dataTask resume];

使用NSUrlSession ...このURLからデータをフェッチして助けてくださいIOSの新たなんだ：

NSString *urlString = @"http://api.openweathermap.org/data/2.5/forecast/daily?q=Indore&mode=json&units=metric&cnt=10&APPID=fc632e2569dbdbb07ca79e239faa0281"; 
NSURLSession *session = [NSURLSession sharedSession]; 
[[session dataTaskWithURL:[NSURL URLWithString:urlString] completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) { 
    // handle the response 
}] resume];
